Hi All,
I am just doing some fine tuning for our mail system and wondering if our
retry configuration is correct.
Below is what is currently set to, which I am pretty sure is the default for
exim. We run a very large site on exim-3.36
Our /var/spool/mail/input is 16GB and doesn't fluctuate that much, only
slighty. I have graphs of it's size from mrtg
Also whats the best way to run exim and its queue daemon? Currently we're
doing /usr/sbin/sendmail -bd -q1h
Is it better to do /usr/sbin/sendmail -bd and then do a seperate
/usr/sbin/sendmail -q1h or is it better to just combine them both.
Should we be using a lower -qx (minute or hour) setting? Someone mentioned
15m, is too much for our site?
I have also considering using another server for all outgoing mail, so in
theory instead of mailing waiting in /var/spool/input it goes via another
server and sits in the queue on that server.
Are there any associated nasties with doing this? No hosts or sites will
refuse my emails or anything wierd because the sending host isn't listed as
an MX?
Any ideas/comments would be great, thanks
